What is a Bill of Particulars primarily used for?

A Bill of Particulars is primarily used to amplify the pleadings in an action. It serves to clarify and provide more detail about the claims made in the initial pleadings, allowing the opposing party to better understand the specifics of the case they are facing. This additional information can include details about the facts, circumstances, and basis upon which the claims are founded, which helps ensure that all parties are adequately informed and able to prepare their respective cases.

The other options do not accurately reflect the purpose of a Bill of Particulars. For instance, providing a final judgment pertains to the conclusion of the litigation process rather than clarifying initial pleadings. Similarly, dismissing a case or changing the venue of an action are procedural actions that do not involve the amplification or clarification of claims. Thus, the primary role of a Bill of Particulars is firmly rooted in enhancing the clarity and specificity of the initial pleadings in an ongoing legal action.
